Glymur ({{IPA|is|ˈklɪːmʏr̥|audio=Glymur pronunciation.ogg}}) is a waterfall in Hvalfjarðarsveit, Vesturland, Iceland. It is the second-tallest in the country with a cascade of {{convert|198|m}}. Glymur was long regarded as the tallest until being surpassed by Morsárfoss, a newly measured waterfall near Morsárjökull in 2011.{{cite news|last1=Guðmundsson|first1=Janus Arn|title=Flyst hæsti foss landsins búferlum?|url=http://www.mbl.is/frettir/innlent/2011/06/15/flyst_haesti_foss_landsins_buferlum/|access-date=1 August 2015|agency=Morgunblaðið|date=2011-06-15|language=Icelandic}}

It is situated at the rear end of the Hvalfjörður. Since the opening of the Hvalfjörður Tunnel under this fjord, visitor numbers have dropped.{{citation needed|date=August 2017}}

The river Botnsá {{IPA|is|ˈpɔsːˌauː|}} runs from the Hvalvatn lake and after a short distance the water falls down alongside the Hvalfell mountain into a steep canyon. The waterfall can be accessed from a parking area at the end of the road. Hikers can view the waterfall from marked paths on the east side of the river Botnsá.
